Platelets play a key role in the pathophysiology of coronary artery disease and acute coronary syndromes. Our understanding of platelet function in thrombus formation has increased considerably, resulting in the development of clinically effective treatment strategies and identification of new targets. An underappreciated platelet function is their contribution toward acute and chronic inflammatory processes including atherogenesis. In this review, we discuss the role of platelets in atherosclerosis and thrombosis, platelet function testing, and the pharmacology of currently available antiplatelet drugs...

BACKGROUND: The chronic effects of ST-segment elevation myocardial infarction (STEMI) on the atrioventricular conduction (AVC) system have not been elucidated. This study aimed to evaluate the incidence, predictors, and outcomes of worsened AVC post-STEMI in patients treated with a primary percutaneous coronary intervention (PCI). PATIENTS AND METHODS: The current analysis included patients from the HORIZONS-AMI trial who underwent primary PCI and had available ECGs...

BACKGROUND: Coronary collaterals are an alternative source of blood supply to ischemic myocardium. Well-developed coronary collateral arteries in patients with coronary artery disease (CAD) limit the size of acute myocardial infarction and improves survival. The aim of this study was to investigate the relationship between glycemic variability and coronary collateral formation in patients with type 2 diabetes mellitus and CAD. METHODS: Consecutive patients undergoing percutaneous coronary intervention or coronary artery bypass grafting procedures were studied...

BACKGROUND: The cause for discrepancy in the clinical presentation and outcome of coronary artery disease (CAD) between men and women is not established. Different prevalences of risk factors or specific sex-related atherosclerotic aspects have been advocated as possible explanations. We investigated coronary plaque morphology looking at possible differences in plaque vulnerability between men and women with stable CAD. PATIENTS AND METHODS: We retrospectively collected and analyzed clinical data and coronary plaque morphology by frequency-domain optical coherence tomography in men and women with stable CAD...

Although drug-eluting stents (DES) have markedly reduced the incidence of stent restenosis (SR), the increased number and complexity of percutaneous coronary interventions performed worldwide explain the sustained prevalence of SR. Intracoronary imaging techniques remain essential tools to unravel the underlying mechanical causes potentially leading to SR. Current clinical trial data suggest that DES are the most effective therapy for the management of both bare-metal stents SR and DES-SR. In this setting, however, drug-eluting balloons represent a valid therapeutic alternative with the attractive advantage of not requiring the implantation of an additional metallic layer...

OBJECTIVE: The aim of this study was to evaluate the association between the mean platelet aggregation degree and long-term clinical outcomes in patients receiving a complex percutaneous coronary intervention (CPCI). PATIENTS AND METHODS: We screened 2141 patients after a percutaneous coronary intervention (PCI) treated with aspirin and clopidogrel. CPCI was defined as a procedure targeted to at least one of the following: left main disease, bifurcation lesion, ostial lesion, chronic total occlusion, and small-vessel stenting...

BACKGROUND: The aim of this study was to identify the prognostic predictors for the worse clinical outcomes after a successful chronic total occlusion (CTO) intervention with drug-eluting stents. PATIENTS AND RESULTS: A total of 2334 patients in the multicenter Korean CTO registry who underwent a successful CTO intervention with drug-eluting stents (first generation, 1367, new generation, 967) were enrolled. The primary endpoint was the composite of cardiac death, myocardial infarction, and stent thrombosis...

Up to 50% of patients presenting with ST elevation myocardial infarction (STEMI) are found to have multivessel coronary artery disease. These patients have a worse prognosis compared with the overall STEMI population. Two revascularization strategies are possible for these patients: treating the infarct-related artery percutaneous coronary intervention (IRA-PCI) only or achieving Complete revascularization (CR), either through an immediate multivessel PCI during the index angiography or during a second-staged procedure...

INTRODUCTION: During the last decade, there has been an increased awareness of sex differences in the clinical characteristics, management, and mortality in myocardial infarction. Many previous studies have found that women with ST-elevation myocardial infarction (STEMI) have a poorer baseline risk profile, are less intensively treated, and have worse outcomes. OBJECTIVE: To evaluate whether sex disparities in STEMI have changed in recent years. METHODS: This is a retrospective analysis of data on 111 148 STEMI patients enrolled in the Polish Registry of Acute Coronary Syndromes between 2005 and 2011...

BACKGROUND: Myocardial infarction is frequently the initial form of presentation of coronary artery disease (CAD). Systemic Coronary Risk Estimation (SCORE) risk tables are used in primary prevention and provide an estimate of cardiovascular (CV) risk through known risk factors. The aim of this study was to evaluate the performance of the SCORE, calculated using data previous to the event, to estimate CV risk of a population of patients presenting with ST-elevation myocardial infarction (STEMI) as the first manifestation of CAD...

BACKGROUND: The presence of good coronary collateral circulation (CCC) can protect and preserve myocardium from ischemia, increase myocardial contractility, and reduce adverse clinical events. However, its impact on mortality is still a topic of debate, particularly in acute coronary syndrome (ACS). The aim of this study was to investigate the association of CCC with cardiac risk factors and in-hospital mortality in patients hospitalized with a diagnosis of ACS. METHODS: The study population included 2286 patients with ACS who underwent coronary angiography and were found to have at least 90% significant lesion in at least one major coronary artery...
